The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™ wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.

FIG. 2 is a diagram illustrating example electronic devices according to various embodiments.

Referring to FIG. 2 , an electronic device according to various embodiments may be implemented as a smartphone 210, a tablet PC 220, a TV set 230, a laptop computer 240, a monitor 250, or the like. Although various embodiments will be described based on specific types of electronic devices (e.g., a laptop, a monitor, and a TV set) in this disclosure, corresponding embodiments may be applied to other types of electronic devices (e.g., a tablet PC or a smartphone).

According to various embodiments, an electronic device may include an expandable display. For example, when a display is in a slide-in state, only a partial area (e.g., a main display area) of the display may be exposed (e.g., visible) to the outside so as to output a screen (211, 221, or 231), and the remaining area (e.g., an expandable display area) received inside the housing so as not be exposed to the outside may not output a screen in an inactive state. The terms “exposed” and “visible” when referring to a display herein may be used interchangeably and include a case where the display or screen is covered by a cover glass, cover layer or other protective sheet) When the display slides out, at least a portion of the area, which is not exposed (e.g., visible) to the outside in the slide-in state, may be exposed (e.g., visible) to the outside (215, 225, or 235), and such extended areas 215, 225, and 235 may switch to an active state, thereby displaying a screen.

FIGS. 3A, 3B, 3C and 3D are diagrams illustrating example structures of an expandable display of an electronic device according to various embodiments.

Hereinafter, although the structure of a tablet PC having an expandable display will be described with reference to FIGS. 3A, 3B, 3C and 3D, other types of devices (e.g., a laptop PC, a monitor, a TV set, and a smartphone) may also have an expandable display the same as or similar to the same.

Referring to FIGS. 3A, 3B, 3C, and 3D, in an embodiment, an electronic device 300 may be implemented to expand a screen 3301 in a sliding type. For example, the screen 3301 (or a main display area) may be an area of a flexible display 330, which is visible to the outside. FIGS. 3A and 3B illustrate the electronic device 300 in the state (e.g., a slide-in state) where the screen 3301 is not expanded (or hidden in a housing), and FIGS. 3C and 3D illustrate the electronic device 300 in the state (e.g., a slide-out state) where the screen 3301 is expanded (or exposed to outside). The state in which the screen 3301 is not expanded indicates the state in which a sliding plate 320 for a sliding motion of the display 330 is not in a slide-out state and may be referred to as a closed state hereinafter. The state in which the screen 3301 is expanded indicates the state in which the screen 3301 is maximally expanded by sliding-out of the sliding plate 320 so that the screen 3301 is no longer expanded, and may be referred to as an open state hereinafter. For example, sliding out may indicate at least partial movement of the sliding plate 320 in a first direction (e.g., the +x-axis direction) when the electronic device 300 switches from the closed state to the open state. According to various embodiments, the open state may be defined as a state in which the screen 3301 is expanded compared to the closed state and may provide screens of various sizes depending on the movement position of the sliding plate 320. According to various embodiments, an intermediated state may indicate a state between the closed state in FIG. 3A and the open state in FIG. 3C. The screen 3301 may include an active area of the flexible display 330 that is visually exposed and capable of outputting images, and the electronic device 300 may adjust the active area according to the movement of the sliding plate 320 or the movement of the flexible display 330. In the following description, the open state may indicate a state in which the screen 3301 is maximally expanded. In various embodiments, the flexible display 330 that is disposed to slide in the electronic device 300 in FIG. 3A and provides the screen 3301 may be referred to as a “slide-out display” or an “expandable display. According to various embodiments, the electronic device 300 including the flexible display 330 may include the electronic device 101 shown in FIG. 1 .

According to an embodiment, the electronic device 300 may include a sliding structure related to the flexible display 330. For example, if the flexible display 330 moves a configured distance by an external force, it may switch from the closed state to the open state or from the open state to the closed state without any further external force due to an elastic structure included in the sliding structure (e.g., semi-automatic sliding operation).

According to an embodiment, if a signal is generated through an input device included in the electronic device 300, the electronic device 300 may switch from the closed state to the open state or from the open state to the closed state due to a driving device such as a motor connected to the flexible display 330. For example, if a signal is generated through a hardware button or a software button provided through a screen, the electronic device 300 may switch from the closed state to the open state or from the open state to the closed state.

According to various embodiments, if signals are generated from various sensors such as a pressure sensor, the electronic device 300 may switch from the closed state to the open state or from the open state to the closed state. For example, a sensor may detect a squeeze gesture in which a part of the hand (e.g., the palm or a finger) presses a specified section of the electronic device 300 when carrying or holding the electronic device 300 by hand, and in response thereto, the electronic device 300 may switch from the closed state to the open state or from the open state to the closed state.

According to an embodiment, the sliding plate 320 may include a third rim 320 b forming an outer surface of the electronic device 300 (e.g., a surface exposed to the outside to form the exterior of the electronic device 300). For example, the third rim 320 b may form a bezel around the screen together with the first rim 313 d and the second rim 314 b in the closed state shown in FIG. 3A. The third rim 320 b may extend in a second direction (e.g., the y-axis direction) to connect one end of the first side cover 313 and one end of the second side cover 314 in the closed state. For example, the surface of the third rim 320 b may be smoothly connected to the surface of the first rim 313 d and/or the surface of the second rim 314 b in the closed state shown in FIG. 3A,

According to an embodiment, due to sliding-out of the sliding plate 320, at least a portion of the bendable section {circle around (2)} may come out from the inside of the electronic device 300 to provide the state (e.g., the open state) in which the screen 3301 is expanded as shown in FIG. 3C.

According to an embodiment, in the closed state shown in FIG. 3A, the screen 3301 may include a flat portion 330 a, and a first curved portion 330 b and/or a second curved portion 330 c positioned on the opposite sides of the flat portion 330 a interposed therebetween. For example, the first curved portion 330 b and the second curved portion 330 c may be substantially symmetrical with respect to the flat portion 330 a interposed therebetween. For example, in the closed state shown in FIG. 3A, the first curved portion 330 b and/or the second curved portion 330 c may be positioned to correspond to the curved portions 313 b and 212 c of the back cover 312, respectively, and may be curved toward the back cover 312. When switching from the closed state shown in FIG. 3A to the open state shown in FIG. 3C, the flat portion 330 a may be extended.

Here, the main content may be content produced when the electronic device 500 executes an application (e.g., an Internet browser, a game, or a gallery). Alternatively, in the case where the electronic device 500 is implemented as a TV, it may be broadcast content received through terrestrial or cable channels. In the state in which the display 530 is not expanded, the expandable display area may be received (or hidden) inside the housing, and the processor 510 may perform control such that the expandable display area is in an inactive state.

According to various embodiments, the processor 510 may identify a connection with an external device for sharing content through the communication module 540 and detect activation of a video sharing function. For example, an external device may be connected through a wired interface (e.g., HDMI or USB) and may be connected through short-range wireless communication such as Wi-Fi Direct, Wi-Fi Aware, and Bluetooth.

According to various embodiments, the processor 510 may receive information related to shared content (or second content) from an external device. For example, when the electronic device 500 and an external device are connected via Miracast, content of the external device may be transmitted as it is and mirrored on the electronic device 500, and when they are connected in a desktop experience (Dex) mode, application information for implementing a UI on the electronic device 500 may be received, or link information to another external device (e.g., an external server) may be received to obtain shared content from another external device.

According to an embodiment, if the electronic device 500 displays a screen displayed on an external device by mirroring, the electronic device 500 may provide, in real time, information (e.g., chatting, SNS, real-time search, etc.) that changes in real time in the external device through an area of the expanded display 530. For example, if the electronic device 500 performs mirroring on a plurality of external devices for screens of the respective external devices, the electronic device 500 may display the screens of the respective external devices in different areas of the expanded display 530 from each other. In this case, the area where the screen of each external device is displayed on the expanded display 530 may be determined based on the position of user interaction using each external device (e.g., left NFC tagging and right NFC tagging of the display).

According to an embodiment, if the electronic device 500 receives link information from an external device and obtains shared content from another external device (e.g., an external server), the electronic device 500 may display, in real time, image information received in real time from the another external device through an area of the expanded display 530. According to the embodiment, a user may interact (e.g., left NFC tagging and right NFC tagging of the display 530) with various areas of the electronic device 500 using a single external device to transmit link information about an image, which is to be transmitted, several times, and the electronic device 500 may receive a plurality of pieces of image information in real time through the link information obtained according to each interaction and display the same in different areas. According to various embodiments, the processor 510 may determine a first area to display the main content and a second area to display the shared content in the state in which the expandable display area is expanded.

According to various embodiments, if the expandable display area is exposed to outside, the processor 510 may determine the main display area to be a first area to display the main content and determine the expandable display area to be a second area to display the shared content. In this case, the main content continues to be displayed on the same position before and after the expansion of the display 530, and the shared content may be displayed in expandable display area that is expanded in any one of the upward, downward, left, and right directions.

According to various embodiments, the processor 510 may determine the first area to display the main content and the second area to display the shared content, based on the user interaction.

According to an embodiment, the processor 510 may determine the first area and the second area, based on a touch or proximity input onto the sensor 550 disposed around the display 530 (e.g., in a corner of the housing or a bezel area). For example, the electronic device 500 may include four NFC sensors 550 on the upper, lower, left, and right sides of the display 530, and if a user's proximity is detected by a specific NFC sensor 550, the electronic device 500 may determine to display the shared content in an area corresponding to the position of the corresponding NFC sensor 550 on the expanded display 530. This embodiment will be described in more detail with reference to FIG. 8 .

According to an embodiment, the processor 510 may determine the first area and the second area, based on a touch input onto the main display area. The display 530 may be configured as a touch screen, and the processor 510 may divide the main display area of the display 530 into a plurality of areas, and if a user's touch input is detected in one of the divided areas, the processor 510 may determine to display the shared content in the corresponding area. This embodiment will be described in more detail with reference to FIGS. 7A to 7C.

According to an embodiment, the processor 510 may recognize a user's gesture, based on image information obtained through the camera 560, and determine to display the shared content in an area corresponding to the user's gesture.

According to an embodiment, the processor 510 may determine the first area and the second area, based on information received from an external device. The external device may execute an application supporting a function of sharing a screen with the electronic device 500, and the application may provide a UI for determining an area where the shared content is to be displayed on the expanded display 530 of the electronic device 500. The electronic device 500 may receive information about selection on the UI of the external device and determine to display the shared content in the corresponding area. This embodiment will be described in more detail with reference to FIGS. 9A and 9B.

According to various embodiments, the processor 510 may determine an area to display the shared content, further based on a display orientation of the shared content. For example, if content displayed on an external device is mirrored on the display 530 of the electronic device 500 such as Miracast, the external device may transmit orientation information obtained through an inertial sensor (e.g., an acceleration sensor or a gyro sensor) to the electronic device 500, and the processor 510 may determine whether to display the shared content in a landscape mode or a portrait mode, based on the received orientation information. Alternatively, the processor 510 may obtain the state of a screen and content input in the application of the external device and/or a display orientation mode provided by the content, and determine the display orientation of the shared content.

According to various embodiments, if the first area to display the main content and the second area to display the shared content are determined, the processor 510 may control the expandable display area of the display 530 to be expanded. For example, the display 530 may be configured such that at least one expandable display area is expanded by a motor structure, and in this case, the processor 510 may automatically expand the expandable display area corresponding to the size of the area to display the main content and the shared content. Alternatively, the display 530 may be configured to be manually expanded by a user's force, and the processor 510 may provide information guiding the user to exposing the expandable display area to the main display area.

According to various embodiments, the processor 510 may determine a screen display type for displaying the main content and the shared content on the expanded display 530. For example, the processor 510 may determine to display content focusing on the main content such that the display area of the shared content is added to the expanded display 530 while maintaining the display area of the main content, display content such that the display area of the main content and the display area of the shared content have the same size, or display content focusing on the shared content such that the display area of the shared content is added by changing (e.g., reducing) the display area of the main content. This embodiment will be described in greater detail below with reference to FIG. 13 .

According to various embodiments, if the first area to display the main content and the second area to display the shared content are determined, the processor 510 may adjust the sizes of the main content and/or the shared content. For example, if it is impossible to display the first content in the same size as the previous one even on the expanded display 530 as the second content is further displayed, the processor 510 may reduce the main content while maintaining the aspect ratio. Alternatively, the processor 510 may display only a portion of the main content by cutting out portions of the main content on the upper and lower sides or the left and right sides thereof, or change the aspect ratio (or resolution) of the main content to match the size of the determined first area.

According to various embodiments, the display 530 may include a first expandable display area that is expandable in a first direction from the main display area and a second expandable display area that is expandable in a second direction. For example, the display 530 may include a first expandable display area and a second expandable display area that are expandable to the left and right, respectively. According to various embodiments, if a position to display the shared content is determined by user interaction, the processor 510 may perform control such that an expandable display area corresponding to the position is expanded. For example, if the display 530 is expandable to the left and right and if the shared content is determined to be displayed on the left side of the main content through user interaction, the processor 510 may control a motor structure such that the left side of the display 530 is exposing to outside or display guide information guiding the user to exposing the left expandable display area.

According to various embodiments, the electronic device 500 may be connected to a plurality of external devices and display shared content shared with the plurality of external devices on the expandable display area. For example, if user interaction occurs on the left side of the display 530 for a first external device and on the right side thereof for a second external device, the processor 510 may display first shared content received from the first external device in a first expandable display area that is expanded to the left of the main display 530 and display second shared content received from the second external device in a second expandable display area that is expanded to the left side of the main display 530. On the other hand, if the electronic device 500 includes an expandable display area that is expanded only in one direction, the processor 510 may divide at least a portion of the expandable display area and the main display area and display the first shared content and the second shared content together with the main content. This embodiment will be described in detail with reference to FIG. 16 .

FIG. 6 is a diagram illustrating an electronic device and an external device supporting a screen sharing function according to various embodiments.

FIG. 6 shows that a user watches a movie as main content in the state (i.e., a slide-in state) in which a display of an electronic device 600 (e.g., the electronic device 500 in FIG. 5 ) is not expanded and, at the same time, identifies movie information from a website related to the corresponding movie through an external device 690. Referring to FIG. 6 , although the external device 690 is illustrated in the form of a smartphone and the electronic device 600 is illustrated in the form of a monitor, they are not limited thereto, and the electronic device 600 may be implemented as various types of devices (e.g., the TV 230, the tablet PC 220, the smartphone 210, the laptop computer 240, and the monitor 250 in FIG. 2 ) having an expandable display

According to various embodiments, the electronic device 600 may be connected to the external device 690 by wired or wireless communication. For example, the electronic device 600 and the external device 690 may be connected through a wired interface (e.g., HDMI or USB) or may be connected through short-range wireless communication such as Wi-Fi Direct, Wi-Fi Aware, and Bluetooth.

According to various embodiments, if a screen sharing event occurs while main content (e.g., a movie) is being displayed on the display, the electronic device 600 may determine an area to display shared content and, according to the determination, perform control such that the display is expanded or provide guide information guiding the user to expand the display.

FIGS. 7A, 7B and 7C are diagrams illustrating example division of areas in which content is displayed on a display according to various embodiments.

According to various embodiments, an electronic device (e.g., the processor in FIG. 5 ) may determine a first area to display main content and a second area to display shared content, based on a touch input onto the main display area and/or an input to a sensor disposed on the side surface of the display. For example, if the main display area of the display is divided into a plurality of areas and if a user's touch input is detected in any one of the divided areas, it may be determined to display shared content in the corresponding area. Here, a method of dividing the area of the main display may be various.

For example, referring to FIG. 7A, a main display area 710 may be divided into three areas on a center 714, a left side 712, and a right side 716. If screen sharing is started and if a user interaction with the left area 712 (e.g., a touch input to the left area 712 of the main display or a proximity input to a sensor disposed on the left side) is detected, the electronic device may determine to display the shared content in the left area in the state (i.e., a slide-out state) in which the display is expanded (e.g., the expandable display area expanded to the left). In this case, the electronic device may control the expandable display area that is automatically expanded to the left to slide out by a motor structure or display information guiding the user to expand the expandable display area to the left on the display. Thereafter, if extension of the display is completed, the previously displayed main content may continue to be displayed on the main display area, and the shared content received from an external device may be displayed on the expandable display area.

In the example shown in FIG. 7A, if a user interaction occurs in the right area 716 in the case where the display is expandable only to the left, the electronic device may display, in the state in which the display is expanded, the shared content on a partial area of the right side of the main display area and may move and display the main content to and on the rest of the main display area and the expandable display area expanded to the left.

According to an embodiment, as shown in FIG. 7B, a main display area 720 may be divided into four areas on a left side 722, a right side 728, an upper side 724, and a lower side 726, and in this case, the shared content may also be displayed at a position corresponding to an area where a user interaction occurs as in the embodiment in FIG. 7A.

According to an embodiment, as shown in FIG. 7C, a main display area 730 may be divided into five areas on a left side 734, a right side 739, an upper side 732, a lower side 738, and a center 736, and in this case, the shared content may be displayed at a position corresponding to an area where a user interaction occurs as in the embodiment in FIG. 7A.

FIG. 8 is a diagram illustrating a sensor for selecting an area of an electronic device according to various embodiments.

According to various embodiments, the electronic device 800 may include one or more sensors 852 and 854 disposed around a display (e.g., a corner of a housing or a bezel area) and capable of detecting a user interaction (e.g., proximity, touch, and the like).

Referring to FIG. 8 , respective sensors may be disposed in four areas on the upper, lower, left, and right sides of the display. The sensors 852 and 854 may include various types of short-range sensors that detect the proximity or contact of an object, such as near-field communication (NFC), radio frequency identification (RFID), Bluetooth (or Bluetooth low energy), or a touch sensor.

According to an embodiment, the sensors 852 and 854 may be NFC tags, and an external device may include an NFC reader and tag an NFC tag disposed in the electronic device 800. For example, when the external device executes a screen sharing application, an NFC reader may be activated, and the user may make the external device approach an NFC tag corresponding to an area where shared content is to be displayed, thereby performing tagging. The NFC tag may include position information of the display, and for example, if an external device 890 tags an NFC tag 852 on the left side of the main display area, selection information of the left area and identification information of the external device 890 may be transmitted to the electronic device 800 through a wireless connection, and the electronic device 800 may control the expandable display area on the left side to be expanded to display the shared content of the external device 890.

In addition, if the user tags a right NFC tag 854 through another external device 895, the external device 895 may transmit selection information of the right area and identification information to the electronic device 800, and the electronic device 800 may control the expandable display area on the right side to be expanded to display the shared content of the corresponding external device 895.

Accordingly, if the display is entirely expanded, the main content and at least one piece of shared content received from at least one external device may be simultaneously displayed.

According to an embodiment, in the case where the electronic device 800 displays a screen displayed on an external device by mirroring, interaction may occur in different areas through two external devices 890 and 895 so that the screens of two external devices may be mirrored in real time on different areas of the expanded display as described above.

According to an embodiment, the electronic device 800 may receive link information from the external device 890 and obtain shared content from another external device (e.g., an external server) through the link information, and the user may make interaction with multiple areas of the electronic device 800 using a single external device 890 to transmit link information of an image to be transmitted several times.

FIGS. 9A and 9B are diagrams illustrating an interface capable of configuring a screen position of an external device according to various embodiments.

According to various embodiments, an external device 900 may execute an application 930 supporting a function of sharing a screen with an electronic device. The application 930 may provide a UI for configuring the position and/or display orientation of the shared content during screen sharing, a UI for configuring the display type of the main content and the shared content, and/or a UI for configuring the size of the content.

Referring to FIG. 9A, a display of the electronic device may include a first expandable display area that is expandable to the left and a second expandable display area that is expandable to the right, and information about the display of the electronic device may be transmitted to the external device 900 through a wired/wireless connection established when the screen sharing function is executed. The external device 900 may display an object 971 indicating the first expandable display area and an object 972 indicating the second expandable display area with reference to display information of the electronic device, and may display an object 973 capable of changing the display orientation (e.g., landscape mode or a portrait mode) of the shared content. For example, if the user selects the object 972 indicating the second expandable display area on the right side from the application 930, corresponding information may be transmitted to the electronic device, and the electronic device may expand the second expandable display area to display the shared content received from the external device 900 at the corresponding position.

According to an embodiment, the external device 900 may include a sensor that detects a tilt of the external device 900 and select an expandable display area to display the shared content according to a tilt direction of the external device 900. For example, if the user tilts the external device 900 to the left, the first expandable display area expandable to the left of the main display area in the electronic device may be determined as an area to display the shared content.

According to an embodiment, the external device 900 may determine an expandable display area to display the shared content, based on a direction of a user gesture (e.g., swipe or flick) on the application 930.

Referring to FIG. 9B, if the user of the external device 900 selects an object 983 capable of changing the display orientation of the shared content, the display orientation of the shared content may be changed from a portrait mode to a landscape mode. In response to the user selection, the object 981 indicating the first expandable display area of the application 930 and the object 982 indicating the second expandable display area of the application 930 may also switch to the landscape mode, and display orientation information may be transmitted to the electronic device. The electronic device may determine the display area of the shared content and/or the extension size of the first expandable display area depending on the received display orientation information.

According to an embodiment, the external device 900 may transmit current orientation information of the external device 900 displaying the shared content, the state of the content, and/or a display orientation mode provided by the content to the external device 900, and the electronic device may determine the display orientation of the shared content, based on the received information.

FIGS. 10A, 10B and 10C are diagrams illustrating an interface capable of configuring a content representation mode in an external device according to various embodiments.

According to various embodiments, an external device 1000 may provide a UI for configuring a display type of main content and shared content in an application. Here, the display type may include a mode of displaying content focusing on the main content, a mode of displaying the main content and the shared content at the same ratio, and/or a mode of displaying content focusing on the shared content.

FIG. 10A illustrates an example of a menu capable of specifying a display type of a screen before the external device 1000 executes screen sharing with the electronic device.

Referring to FIG. 10A, the external device 1000 may provide a description of each mode in an application and graphic information 1072, 1074, and 1076 thereof, and if one mode is selected according to a user input (1072), information on the selected mode may be transmitted to the electronic device. For example, the external device 1000 may provide a menu for selecting a first mode 1072 in which content is displayed focusing on the main content of the electronic device, a second mode 1074 in which the main content of the electronic device and the shared content of the external device are displayed in substantially the same size, and a third mode 1076 in which content is displayed focusing on the shared content of the external device. If the user selects not-configure 1078 from the menu in FIG. 10A, the external device 1000 may provide a UI for selecting a mode when the content is actually shared with the electronic device.

FIG. 10B illustrates a UI for selecting a mode when content is shared with the electronic device. The external device 1000 may provide menu for selecting a first mode 1073 in which content is displayed focusing on the main content of the electronic device, a second mode 1075 in which the main content of the electronic device and the shared content of the external device are displayed in substantially the same size, and a third mode 1079 in which content is displayed focusing on the shared content of the external device.

An example in which the electronic device displays the shared content and the main content on the expanded display according to the mode selected through the UI in FIG. 10A or 10B will be described in more detail with reference to FIG. 13 .

According to various embodiments, the external device 1000 may provide a UI for configuring the size (or ratio) of content in an application. The electronic device may expand the display to display the shared content, but the size or aspect ratio of the expandable display area may be different from that of the shared content.

Referring to FIG. 10C, examples of a representation mode of content may include a mode of displaying all content, a mode of displaying content in an optimal size, and a mode of displaying content in a maximum size. For example, the mode of displaying all content 1082 may be a mode in which all of the shared content is displayed on the display area (or second area) of the shared content while maintaining the aspect ratio of the shared content and in which the area where the shared content is not displayed due to a difference of the aspect ratio is processed to be black. The mode of displaying content in the optimal size 1084 may be a mode in which a portion of one side of the shared content in the horizontal or vertical direction, which is greater than the display area, is cut out and the remaining portions are displayed. The mode of displaying content in the maximum size 1086 may be a mode of displaying the shared content by changing the resolution thereof to the maximum size according to the display area of the shared content without maintaining the aspect ratio of the shared content. The external device 1000 may provide information on a mode selected by the user in an application to the electronic device, and the electronic device may determine a representation mode of the shared content according to the mode information.

FIG. 11A is a flowchart illustrating an example method of providing content in an electronic device according to various embodiments.

The illustrated method may be performed by an electronic device (e.g., the electronic device 500 in FIG. 5 ) including the above-described expandable display (e.g., the display 400 in FIGS. 4A to 4E), and descriptions of technical features made above may not be repeated here.

According to various embodiments, an electronic device (or a main device) may display main content (or first content) on a main display area of a display in the state in which the display is not expanded. (1101)

According to various embodiments, the electronic device may detect a user interaction using an external device and identify a display position of shared content on an expanded display according to the user interaction. For example, the electronic device may determine one of a left area, an upper area, a center area, a lower area, and a right area as the display position of the shared content. (1103)

According to various embodiments, the electronic device may identify a screen orientation state of the external device. For example, the screen orientation state may be any one of a vertical screen orientation state (or a portrait mode) and a horizontal screen orientation state (or a landscape mode). (1105)

Although FIG. 11A illustrates that operation 1105 is performed after operation 1103, the display is not limited thereto, and operation 1103 may be performed after operation 1105 or, at least in part, simultaneously therewith.

According to various embodiments, the electronic device may select a screen display type and a representation mode. (1107) For example, the user may select a screen display type and a representation mode through the user interface shown in FIGS. 9A, 9B, 10A, 10B, and 10C using the external device, and the external device may transmit the selected information to the electronic device.

If the display area, display orientation, and/or display type of the main content and shared content are determined, the electronic device may determine the extension length of the expandable display area and expand the display, thereby displaying the main content and shared content. (1109)

FIG. 11B is a flowchart illustrating an example method of providing content in an electronic device according to various embodiments.

The illustrated method may be performed by an electronic device (e.g., the electronic device 500 in FIG. 5 ) including the above-described expandable display (e.g., the display 400 in FIGS. 4A to 4E), and descriptions of technical features made above may not be repeated here.

According to various embodiments, an electronic device (or a main device) may display main content (or first content) on the main display area of a display in the state in which the display is not expanded (1110). For example, the main content may include content produced by an application and broadcast content.

According to various embodiments, an external device (or a sub-device) may be connected to the electronic device through a wired or wireless interface and may execute a screen sharing function according to user interaction (1115).

According to various embodiments, the electronic device may determine an area to display shared content according to the user interaction. The electronic device may identify the area of the display of the electronic device where the user interaction occurred (1120). For example, the display may be divided into four areas on the left, right, upper, and lower sides in an unexpanded state, and the electronic device may determine one of a left area 1122, an upper area 1124, a central area 1125, a lower area 1126, and a right area 1128 to be the position thereof depending on the user interaction.

According to various embodiments, in the state in which a screen sharing function is executed, the electronic device may determine an area to display shared content, based on an interaction on a sensor (e.g., a touch sensor, NFC, Bluetooth, or a camera) disposed in the electronic device, a touch input onto the main display area, and/or an external device.

According to various embodiments, the electronic device may determine display orientation of the shared content (1130). The electronic device may determine the display orientation of the shared content as a vertical screen orientation state (or a portrait mode) 1132 or a horizontal screen orientation state (or a landscape mode) 1134. For example, the external device may transmit orientation information obtained through an inertial sensor (e.g., an acceleration sensor or a gyro sensor) to the electronic device, and the electronic device may determine whether to display the shared content in a landscape mode or a portrait mode, based on the received orientation information. Alternatively, the electronic device may obtain the state of a screen and content input in the application of the external device and/or a display orientation mode provided by the content and determine the display orientation of the shared content.

According to an embodiment, the electronic device may select a display position of the shared content according to user interaction after determining the screen providing orientation of the external device (1120, 1122, 1124, 1125, 1126, and 1128). (1130, 1132, and 1134)

According to various embodiments, the electronic device may select a display type and a representation mode of content (1140). The external device may provide a UI for configuring a display type of main content and shared content in an application and determine a display type of content according to a user input. Here, the display type may include a mode 1142 of displaying content focusing on the main content, a mode 1144 of displaying the main content and the shared content at the same ratio, and/or a mode 1146 of displaying content focusing on the shared content. If the mode 1146 of displaying content focusing on the shared content is selected, the electronic device may determine a display area in a manner of adding the area of the shared content of the external device while changing (or reducing) the main content area of the electronic device as the size of the shared content is increased.

According to various embodiments, if the display area, display orientation, and/or display type of the main content and the shared content are determined, the electronic device may determine an extension length of the expandable display area (1150).

According to various embodiments, the electronic device may execute a command to expand or reduce the display (1160). For example, in the case where the expandable display area is configured to be automatically expanded by motor control, or if the display is configured to be manually expanded by user force, the electronic device may provide the main display area with information for guiding the user to expand the expandable display area.

FIG. 12 is a diagram illustrating an example of providing content of an electronic device and content of an external device on a display of the electronic device according to various embodiments.

Referring to FIG. 12 , the user may watch a broadcasting screen through an electronic device 1200 (e.g., a monitor, TV, or a tablet PC) and, at the same time, display an enlarged (close-up) screen in which only a portion of the broadcasting screen is enlarged through an external device 1290 (e.g., a smartphone). According to an embodiment, the electronic device 1200 may receive and display a broadcast in real time through a terrestrial network, a cable network, or the Internet, and the external device 1290 may stream an enlarged screen in real time through an Internet browser or a media application.

According to various embodiments, the user may establish a wireless connection (e.g., Wi-Fi direct, Wi-Fi aware, or Bluetooth) for screen sharing with the external device 1290 and input a user interaction for determining a display area of shared content. For example, if the user tags the external device 1290 onto an NFC tag provided on the right side of a display 1230 of the electronic device 1200, the external device 1290 may transmit information of the recognized NFC tag to the electronic device 1200, and the electronic device 1200 may determine to display the shared content by expanding the right expandable display area.

According to various embodiments, if the display area of the shared content is determined, the external device 1290 may transmit link information of the shared content (e.g., an enlarged screen) to the electronic device 1200, and the electronic device 1200 may access the corresponding link through an Internet browser or a media application to stream the enlarged screen in real time.
